Description

Technical Field

[0001] This utility model relates to the field of lead screw processing equipment, and in particular to an automatic feeding and conveying structure for lead screw processing. Background Technology

[0002] Lead screw machining equipment such as Figure 1 As shown, the chuck 14 clamps the lead screw 4 and drives the lead screw 4 to rotate. The grinding wheel 13 grinds the outer circle of the end of the lead screw 4. After grinding, the chuck 14 releases the lead screw 4, and the lead screw 4 is pushed out of the chuck 14 by the lead screw 4 that is feeding material later.

[0003] The lead screw workpiece ejected from the chuck will fall directly onto the worktable or outer shell of the grinding machine. The lead screw workpiece has a certain length and weight, and during the direct fall, it will have a rigid collision with the grinding machine body, which can easily cause scratches, dents and other damage to the machined outer surface of the lead screw end, and will also accelerate the wear of the grinding machine worktable. At the same time, metal shavings will accumulate on the grinding machine worktable. These shavings can easily get embedded in the thread groove of the lead screw or stick to the machined surface. If they are not cleaned in time, they will cause secondary damage during subsequent transportation or storage, further affecting product quality. Utility Model Content

[0004] To improve the feeding of materials after lead screw machining, this application provides an automatic feeding and conveying structure for lead screw machining.

[0005] The automatic feeding and conveying structure for lead screw machining provided in this application adopts the following technical solution: An automatic unloading and conveying structure for lead screw machining includes a machine base with a machining position for machining the end of the lead screw and an unloading position after the lead screw is pushed out of the chuck. It also includes a guide plate and a conveying mechanism. The guide plate is fixedly mounted on the machine base and is inclined, with its top end directly below the unloading position and its bottom end close to the conveying mechanism. The conveying mechanism has a conveyor belt for receiving the lead screw rolling off the guide plate and conveying it to a designated position.

[0006] By adopting the above technical solution, after the lead screw is pushed out of the chuck, it can be stably supported and guided by the inclined guide plate, which greatly reduces the fall height of the lead screw and avoids the lead screw falling directly and colliding rigidly with the machine tool. After the lead screw rolls off the guide plate, it is transported away by the conveyor belt, realizing the automated connection of the lead screw from the completion of processing to the centralized unloading point, which greatly improves production efficiency and the orderliness of unloading.

[0007] Preferably, the guide plate is located outside the processing position.

[0008] By adopting the above technical solution, the guide plate is positioned outside the machining station, effectively avoiding the grinding wheel's machining area and preventing it from interfering with the machining process. It also avoids, to some extent, the main falling area of ​​flying debris during grinding, thus reducing the likelihood of metal debris falling onto the guide plate. This also helps maintain the cleanliness of the guide plate surface and reduces contamination of the leadscrew.

[0009] Preferably, the front of the guide plate is used to receive the lead screw, and two bent mounting pieces are fixed to the back of the guide plate. One end of the mounting piece is welded to the back of the guide plate, and the other end of the mounting piece is fixed to the machine base by screws.

[0010] By adopting the above technical solution and connecting them with bent mounting plates, the guide plate is provided with stable support and can withstand the impact of the falling screw. On the other hand, this installation method also facilitates the adjustment of the guide plate's position and disassembly and maintenance, improving the practicality and flexibility of the structure.

[0011] Preferably, the conveying mechanism further includes a mounting strip, a mounting plate, a motor, a baffle, and two rotating rollers. The mounting strip is fixedly mounted on the machine base and located on one side of the machine base. The mounting plate is fixedly connected to the side of the mounting strip away from the machine base. The motor is fixedly mounted on the mounting plate, and the output shaft of the motor is coaxially fixed on one of the rotating rollers. The other rotating roller is rotatably connected to the mounting plate. The conveyor belt is wound around the outer circumference of the two rotating rollers. The two rotating rollers are located between the mounting plate and the machine base and above the mounting strip. The baffle is fixedly mounted on the outside of the mounting plate and is opposite to the guide plate. The baffle is used to limit the lead screw rolling off the guide plate to guide the lead screw onto the conveyor belt.

[0012] By adopting the above technical solution, the baffle ensures that the lead screw falls accurately onto the conveyor belt, preventing it from rolling off the belt and being smoothly transported to the designated position. This achieves automated and orderly transfer of the lead screw from the unloading point to the collection point.

[0013] Preferably, the conveyor belt consists of two conveyor belts.

[0014] By adopting the above technical solution, the lead screw is naturally confined between the two rubber rings when it falls, effectively preventing the lead screw from rolling or deflecting randomly on the transmission rubber rings, thus improving the stability of the conveying.

[0015] Preferably, a limiting plate is fixedly installed on one side of the machine near the mounting strip, the limiting plate and the mounting plate are respectively located on both sides of the conveyor belt, and the top of the limiting plate and the mounting plate are both located above the conveyor belt.

[0016] By adopting the above technical solution, the limiting plate and the mounting plate form protection on both sides of the conveyor belt, together constituting a stable conveying channel, effectively preventing the lead screw from rolling off the side of the conveyor belt during the conveying process, and ensuring the continuity and reliability of the conveying process.

[0017] Preferably, the bottom end of the limiting plate is bent toward the conveyor belt to form a supporting part, which is located below the upper working section of the conveyor belt and is used to support the upper working section.

[0018] By adopting the above technical solution, the support part provides effective bottom support for the upper working section of the conveyor belt, preventing excessive sagging of the conveyor belt that may occur due to the weight of the lead screw, ensuring the smooth operation of the conveyor belt, and helping to extend the service life of the conveyor belt and related components.

[0019] The main technical effects of this utility model are reflected in the following aspects: 1. After the lead screw is pushed out of the chuck, it can be stably supported and guided by the inclined guide plate, which greatly reduces the fall height of the lead screw and avoids the lead screw falling directly and colliding rigidly with the machine tool. After the lead screw rolls off the guide plate, it is transported away by the conveyor belt, realizing the automated connection of the lead screw from the completion of processing to the centralized unloading point. 2. This utility model places the guide plate outside the processing position, which not only effectively avoids the grinding wheel processing area and prevents it from interfering with the processing, but also avoids the main falling area of ​​the flying debris during grinding, thereby reducing the possibility of metal debris falling onto the guide plate.

[0026] The following is in conjunction with the appendix Figures 2-5 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0027] This application discloses an automatic feeding and conveying structure for lead screw machining.

[0028] Reference Figures 2-5 An automatic feeding and conveying structure for lead screw processing in this embodiment includes a machine base 1. The machine base 1 has a processing position 11 for processing the end of the lead screw 4 and a feeding position 12 after the lead screw 4 is pushed out of the chuck 14. It also includes a guide plate 2 and a conveying mechanism 3. The guide plate 2 is fixedly installed on the machine base 1 and is inclined. The top of the guide plate 2 is located directly below the feeding position 12, and the bottom of the guide plate 2 is close to the conveying mechanism 3. The conveying mechanism 3 has a conveyor belt 31, which is used to receive the lead screw 4 rolling off the guide plate 2 and convey it to a designated position.

[0029] Reference Figures 2-5 After the lead screw 4 is pushed out of the chuck 14, it can be stably supported and guided by the inclined guide plate 2, which greatly reduces the fall height of the lead screw 4 and avoids the lead screw 4 falling directly and colliding rigidly with the machine tool. After the lead screw 4 rolls off the guide plate 2, it is carried away by the conveyor belt 31, realizing the automated connection of the lead screw 4 from the completion of processing to the centralized unloading point, which greatly improves the production efficiency and the order of unloading.

[0030] Reference Figures 2-4 The guide plate 2 is located outside the machining station 11. Positioning the guide plate 2 outside the machining station 11 not only effectively avoids the machining area of ​​the grinding wheel 13, preventing it from interfering with the machining process, but also, to a certain extent, avoids the main falling area of ​​flying debris during grinding by the grinding wheel 13, thus reducing the possibility of metal debris falling onto the guide plate 2. This also helps keep the surface of the guide plate 2 clean, reducing contamination of the lead screw 4.

[0031] Reference Figures 2-4 The front of the guide plate 2 is used to receive the lead screw 4, and two bent mounting pieces 21 are fixed on the back of the guide plate 2. One end of the mounting piece 21 is welded to the back of the guide plate 2, and the other end of the mounting piece 21 is fixed to the machine base 1 by screws.

[0032] Reference Figures 2-4 The guide plate 2 is connected by a bent mounting plate 21, which provides a stable support for the guide plate 2 and can withstand the impact of the falling screw 4. On the other hand, this installation method also facilitates the position adjustment and disassembly and maintenance of the guide plate 2, improving the practicality and flexibility of the structure.

[0033] Reference Figures 2-5 The conveying mechanism 3 also includes a mounting strip 32, a mounting plate 33, a motor 34, a baffle 35, and two rotating rollers 36. The mounting strip 32 is fixedly mounted on the machine base 1 by angle iron and is located on one side of the machine base 1. The mounting plate 33 is fixedly connected to the side of the mounting strip 32 away from the machine base 1 by screws. The motor 34 is fixedly mounted on the mounting plate 33 by screws, and the output shaft of the motor 34 is coaxially fixed on one of the rotating rollers 36. The other rotating roller 36 is rotatably connected to the mounting plate 33. The conveyor belt 31 is wrapped around the outer circumference of the two rotating rollers 36. The two rotating rollers 36 are located between the mounting plate 33 and the machine base 1 and are located above the mounting strip 32. The baffle 35 is fixedly mounted on the outside of the mounting plate 33 by screws. The baffle 35 is opposite to the guide plate 2 and is used to limit the lead screw 4 rolling off the guide plate 2 so as to guide the lead screw 4 onto the conveyor belt 31.

[0034] Reference Figures 2-5 The baffle 35 ensures that the lead screw 4 falls accurately onto the conveyor belt 31, preventing it from rolling off the conveyor belt 31, and smoothly conveys it to the designated position via the conveyor belt 31. This realizes the automated and orderly transfer of the lead screw 4 from the unloading position 12 to the collection point.

[0035] Reference Figures 2-5 The conveyor belt 31 consists of two conveyor belts 311. When the lead screw 4 falls, it is naturally restrained between the two belts, effectively preventing the lead screw 4 from rolling or deflecting randomly on the conveyor belts 311, thus improving the stability of the conveying. The rotating roller is provided with annular grooves 361 for the conveyor belts 311 to be embedded and positioned.

[0036] Reference Figures 2-5 A limiting plate 37 is fixedly installed on one side of the machine base near the mounting strip 32 by screws. The limiting plate 37 and the mounting plate 33 are located on both sides of the conveyor belt 31, and the tops of the limiting plate 37 and the mounting plate 33 are both located above the conveyor belt 31.

[0037] Reference Figures 2-5 The limiting plate 37 and the mounting plate 33 form protection on both sides of the conveyor belt 31, together constituting a stable conveying channel, effectively preventing the lead screw 4 from rolling off the side of the conveyor belt 31 during the conveying process, and ensuring the continuity and reliability of the conveying process.

[0038] Reference Figures 2-5The bottom end of the limiting plate 37 is bent toward the side of the conveyor belt 31 to form a support part 371. The support part 371 is located below the upper working section of the conveyor belt 31 and is used to support the upper working section.

[0039] Reference Figures 2-5 The support part 371 provides effective bottom support for the upper working section of the conveyor belt 31, preventing excessive sagging of the conveyor belt 31 that may occur due to the weight of the lead screw 4, ensuring the smooth operation of the conveyor belt 31, and helping to extend the service life of the conveyor belt 31 and related components.

[0040] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
